Be it known that 1, DAVID BEARLY, a citizen of the United States, residing at New Castle, in the county of Henry and State of Indiana, have invented a new and useful Iniprovement in. I lawn-Mowers, of which the fol.- .lowing is a specification.

My invention relates to lawnmowers with two revolving cutters, one placed above and forward of the other, so as to form a double cutter, and also relates to the means for throwing the same in and out of gear and for oper ating the same, and has for its object the construction of a mower to cut higher than mowers usually cut. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a sectionalviewot' the machine, showing the mechanism for throwing the revolving cutters in or out of gear and the position of the revolving cutters and stationary knife-bars in relation to each other. Fig. 2 is a view of one of the drive-wheels, one being used on each side of the mower and being similar in construction, each having a flange near the circumference at right angles to its inner surface, with cogs projecting from the inner surface of flange toward the center of the wheel. Fig. 3 is a view of the reverse side from that shown in Fig. l of the plate B, and shows the position of the cogwheels which revolve the revolving cutters. Fig. 4 is a view of one of the cog-wheels of the revolving cutters, with a cross-section of the axle of the revolving cutter and of the slot, pawl, and devices for throwing the revolving cutters in and out of motion. Fig. 5 is a view of the connecting-bar uniting the two sides of the mower in the rear, which also constitutes a part of the tool-box S attached thereto. Fig. 6 shows in perspective the parts shown in Fig. 1 with the rotary cutters removed, showing the forms of the plates B and carriers C 1), and the position of the stationary knife-bars, and means for regulating the same.

Similar letters represent like parts th roughout the several views.

Two drive-wheels, A, are used, one on each side of the mower. Both are alike. On the inner side, near the circumference of each of these drive-wheels, is a flange at right angles to the face of the wheel with cogs pointing to the axis of the wheel, which cogs and flange are cast as integral parts of the wheel, as shown in Fig. 9.

B B, Figs. 1 and 2, are two like plates, one covering the inner side of each drive-wheel, including the cog-god flanges. Zach of these plates has a narrow flange near its circumference at right angles to the plate on the side that faces away from the drive-wheel. The flange-cogs of the drive-wheels A engage with the cogs of the wheels Ii on the outer ends of the axles of the revolving cutters at each side of the mower when in gear and engaged in cutting.

The plates B B are held in place and in relation to the drive-wheels by means of a central shaft, Q, connecting the two sides of the machine and passing through plates B B and wheels A A.

On the forward edge of each of the plates B is attached the side cutter, M, a thin sharp metal plate, and the lifting-point N, a toothlike projection, for cutting, gathering, and taking up tangled grass which may be in the way of the mower at those points. There is also cast upon each of the plates 13 as an integral part thereof a socket, E, for reception of a handle for pushing the mower when at work. These sockets project beyond the peripheries of the plates B, and each has a slot,

Y, in,the projecting end for regulating the position of the handles by means of bolts passing through the handles and the slots. The handles are pivoted at the lower ends by means of other bolts, X. The handles are made narrower than the space between the two flanges of the sockets E.

In each of the plates B are two slots, H E, Fig. 3, one end of each slot approaching-nearer to the periphery of the plate than the other, so that the wheels U on the axles G and G of the revolving cutters shall, when the axles are in that end of the slot nearest the periphery, engage with the cogs of the flange of the drive-wheel A, but when in the other end of the slot shall not so engage.

is a hollow projecting sleeve or stud for receiving upon it as an axle the drive-wheel A and for the passage through it of the central shaft, Q. In the flange of each of the plates 13 are cut; notches O O t) [or receiving the s n'ing-levers 1 I for th rowing the revolving cutters in or out of gear and to retain them in place.

and l) are carriers lorsupportingthestationar cutt lug-knife hars, revt'ilviug cutters, and the spring-levers i i ()ne of each ot these carriers is pivoted to the inner side of each ot' the plates l) by the pivots l l, which pass through the plate and are securetfl on the 'lo tionarv knit'e-hars K. K hearing the stationary knives K K. i'pon each of the carriers, at a proper place above and in relation to the position of the stationary l nile-hars, are cast two lugs, .l .l, as integral parts thertml', in which are drilled. holes in which are cut screw-t hreads for receiving the setting-screws J .i, for regulating the pitch of the stationary har and knife.

The ends of the axle ot? each revolving cutter pass through the hoxes or holes G G in the carriers and I), that oil the 11])p0l'0ill'li61' through hox (1", and that of the lower cutter through hox G in carrier C, and pass on l'arther end pointing to the ctmter olf wheel, as shown in Fig. -l:. When the axles of the revolving cuttmfs are in place in the carriers and I), and pass through slots ll ll in plates ll ii, and have wheels i in place, thcv may he moved hack and forth in the slots -ll. ii, and he thus thrown in or out ot gear h v motion ol' their respective etu'riers (and II) upon their respective pivots, which motion is (lletlttl hy raising the spring-levers It 1" out; of their respective lltiltller O and moving them till they respeetiveiy rest in 0. These spring-levers may he oi any material such as wood or l]lt}l'ill-;t'lltl need to helit't'ed hut very little to change their position.

The revolving cutters and their knives are such as are used on most lawtrmowers, and are designated V Y Y, &c.

'lfl ig. l, is athin metal plate reaching't'rom side to side of the machine hetween the plates ii, and is slipped in hetween thcrevolving cutters to keep the grass euthy the upper cutter l'rom t'aliing upon and clogging the lower cutter, and is kept in place h v the lugs '1" T cast upon each ot the plates ll. it may he readily rcnnoved and replaced.

The wheel U, pawl \V, and axle G arc shown in Fig. r. The wheels if each have in the circumference of their central hole [Your notches, a, each occupving onc-hmrth ol' the eircum'fcrtience, one end of each inotch commencing flush with. the inner surface of hole and thence deepening toward the circiunterenct'i ot' the wheel to a proper depth and having a square shoulder at the This is ct'tfectctl h v pawls \V, consist They are l drive-wheels A A to the outer sides of each of the d rive-wheels, and is secured in place hva nut or other means and holds the two sides oi the imt'nver together, and is assisted in this work hy the cross-har lit, Fig. 5, whieh gives tirmness and strength to the llli'itllll'lt". This cross-hair is attached at: each side to the han-- die-socket llangcs. ()n the cross-hai- R is a hox, i", with lid, for holding tools-such as screw-driver, oil-can, &c. \Vhen the carriers and l), pivt'lted to each oil the plates 11, the knife-bars, stationary knives, axles of the rtwoiving cutters, and wheels U are all in place, as ahove described, and the two sides of the machine are secured in relation to each other by central shaft, (3, and cross-hat? R,

as above explained, and, the spring-lever l1 rests in notch and the spring-lever F res s in thc notch O, hoth ot? the revolving euttcrs will he out of gear and the cogs ot' the wheels if will not: engage with the cogs on the flanges ot' the drive-wheels, the axles being thrown too far hack in slots ii, i i. It, now, I move the S])lll1 "-l(3\'t l' ill out 013' i'loteh 0' down into ntjrteh t)" in the llangc of each of the plates ll, I thereby move the carrier 0 in that direction, and with it; all parts attached thereto, and the wheel U on each end of the axle G is hrougl'it into engagement with the cogs in the rim-flange of the drive-wheels, and the lower revolving cutter will he in gear and can. he used alone; or it I desire to use hoth cutters I also lift the s j ring-lcvcr 1? out of the lunch 0 in each ol' the plates l3 and carry them to notch O in. plates B, and this will put the upper rev0lv- Lil ing cutter in gear and it will cut at the same time with the other, or the lower revolving cutter may be thrown out of gear, leaving only the upper one in gear, and I may cut with that alone. Each of the revolving cutters may be thrown in or out of gear simul taneously or alternately at will.

I am aware that revolving cutters, stationary bars and knives, cog -gearing, and other devices have been and are used in lmvn-mowers, and I do not claim these separately, and I do not claim-a lawn mowing machine, broadly; but

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is-
